Hello. You should definitely see a doctor and get a X-ray done of the knee to rule out knee fractures
and for the wound care. Motrin
will reduce your pain but not the swelling. And during this time your sugars have to be monitored and adequately controlled or else you might have delayed healing of the wound. Swelling of the calf and numbness
are not good signs, so see a doctor as soon as possible. Get well soon, take care.
